Understanding Your Result
The calculation generated by this tool provides an evidence-based assessment derived from established physiological and clinical equations. Use this measurement as an educational indicator alongside broader lifestyle variables, including overall dietary quality, resistance training, cardiovascular endurance, and routine medical checkups.
Mathematical Formula & Scientific Methodology
WHR is calculated by dividing waist circumference by hip circumference. According to the WHO: High health risk is defined as WHR > 0.90 for men, and WHR > 0.85 for women.
Step-by-Step Example Calculation
Clinical Limitations & Nuances
Ensure hip circumference is measured around the widest portion of the buttocks, keeping the tape parallel to the floor.
Frequently Asked Questions
What does an "apple shape" mean for health?
An "apple" shape (android fat distribution) indicates higher visceral fat stored around abdominal organs, increasing risk for type 2 diabetes and hypertension.
How do I measure my hips correctly for WHR?
Stand upright with feet together and measure at the widest circumference of your buttocks and hips without pulling the tape too tight.
